SUPPORT FOR SPINNING-SPINDLES.

SPECIFICATION forming part of Letters Patent No. 364,897, dated June 14,1887.

- Application filed Jnne1,1886. Serial No. 203,121. (No model.)

Ta'aZZ whom it may concern:

Be it known that 1, WILLIAM T. CARROLL, of Worcester-,county ofWorcester, andState of Massachusetts, have invented an Improvement inSupports for Spinning-Spindles, of which the following description, inconnection with the accompanying drawings, is a specification, likeletters on the drawings representing like parts.

.My invention has for its object to improve that class ofspindle-bearings which are attached to the bolster rail or base at asingle point, and by means of a flexible connection located outside ofthe rail and eccentric to the axial line of the spindle and'its lateralbearings.

My invention consists, essentially, in a bearing, a flexible support orpin to sustain it, and a rail or base to hold the pin, the bearing andpin being connected together in such manner as to utilize the torsionalstrain in the pin.

Figure 1 in vertical section shows a bearing supported in accordancewith my invention upon a rail or base, the spindle being in elevation;and Fig. 2 is a section of Fig. 1 in the line 09 ac, looking downward,the sleevewhirl and spindle being removed.

The bolster-rail A, as herein shown, receives the base B, above which isheld the foot 0 of the bearing 0, the said bearing and foot being arigid and preferably integral piece or casting, having a sleeve, 0 boredto form a hole substantially parallel with relation to thehole in thetube-like part 0 of the bearing, the latter part receiving the pintle aof the spindle a, having attached to it a sleevewhir1,a of usualconstruction, the said whirl surrounding the upright bearing 0. Thesleeve 0 of the bearing referred to is placed over a vertical pin orstud D, extended upwardly from the base B, the said sleeve fitting thesaid pin or stud and being connected therewith by a lockingpin, b, whichis extended through the said sleeve and pin D, as best shown in Fig. 2.The pin or stud D supports the bearing for the spindle above and out ofcontact with relation to the base B and rail A, so that the bearing isfree to yield to a limited extent to; counteract the shock produced atthe foot of the spindle owing to rapid J rotation or unequal loadingthereof. The

bearing is retained in its normal position by the locking-pin b, thesaid pin preventing the bearing from being lifted from the pin or stud Daccidentally. This pin D also serves another very important purpose-viz:\Vhen the bearing 0 and its foot are subjected, through the band-pull,or by reason of other strains, to such strain as would tend'to move thebearing about the stud or pin D, located eccentrically to thelongitudinal axis of the spindle, the locking-pin at such times affordssuch a connection between the sleeve 0 and the said pin or stud D as toenable the tendency of the bearing to move in a circular path about thesaid pin or studD, to be substantially counteracted by the torsionalstrain produced upon the pin onstud D. The hearing 0 is oiled throughthe hole d, which communicates with a channel made in the foot 0.

I claim- A spindle and a sleeve-whirl, the bearing 0 for the spindle,and its connected sleeve 0 combined with a vertical stud or pin tosupport the said bearing, and with means to lock together the saidsleeve and stndor pin, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

WILLIAM T. CARROLL.
